La Fortuna, Costa Rica. Feb 2023 (1 Viewer)

[Cormac]

I consulted Merlin, eBird and books but I am unsure of these seven. All photos are from the La Fortuna area.

3735 - I was told on site that it was a type of Manakin ??
3809 - ??
3843 - Variable Seedeater ??
3102 - Cocoa Woodcreeper ??
3655 - Ochre Bellied Flycatcher ??
4078 - ??
4160 - Dusky-capped Flycatcher or Yellow-bellied Elaenia ??

Would greatly appreciate any assistance.

10 years (!) since I was in CR, but I believe the following are correct:

735 - f/juv white collared manakin (red legs, dusky breast)
809 - Yellow warbler
843 - White lined tanager (I think though the tail looks a bit odd)
102 - Cocoa woodcreeper
655 - Lesser greenlet
078 - pass
160 - Dusky capped flycatcher (I think, but the myiarchus flycatchers are a real pain in the arse!)

Hopefully others with more recent experience can confirm!

Agree

809 - Yellow warbler

I think f common yellowthroat (too dull for yellow warbler)

843 - White lined tanager (I think though the tail looks a bit odd)

Y. Male (note the bicoloured bill)

102 - Cocoa woodcreeper

Y

655 - Lesser greenlet

Imm. Ochre-bellied fly (we can see the double ochre wingbar starting to appear. Still has juv. gape)

078 - pass

Olivaceous woodcreeper

160 - Dusky capped flycatcher (I think, but the myiarchus flycatchers are a real pain in the arse

735. W-C Manakin, bright with orange legs
809. Yellow Warbler, dull female. Note the strong edging on the wing feathers, Common Yellowthroat lacks this showing quite a uniformly unpatterned wing
843. Blue-black Grassquit, different proportions from W-S Tanager with smaller bill
101. Cocoa Woodcreeper
655. Ochre-bellied Flycatcher
078. Likely Olivaceous Woodcreeper
160. Dusky-capped Flycatcher. YB Elania would have a finer bill, lack the darker heard/crown and be paler overall

I thought this initially, but bill does appear bicoloured

For Avery: where would the white in the wing come from if Grassquit?
Compare:

Blue-black Grasquit (male)

Blue-black Grassquit (Volatinia jacarina splendens)

It's something I can recall seeing on them before

The underwing coverts are white. A quick look through ebird images with show several examples where this is visible.

I thought this initially, but bill does appear bicoloured

I'm not so sure of this, the lower mandible only looks paler along the bulge of the curve (front to back) which makes sense as the light would be reflecting directly towards the observer from this part of the bill as it is the part of the bill that is flush to the observer. I realize that is perhaps a bit of an head-scratching statement but I can't think of a better way to describe it at the moment.

Everything else adds up for BB Grassquit, the blue-ish iridescence, the brownish fringing on the body feathers that is typical on freshly moulted (immature?) males, smaller conical bill etc.

Hmm I was going to add this to the Opus page on these species when I thought I'd better just check against Ebird images. Those suggest it's not (always?) the case—outer vanes of flight feathers can be quite strongly yellow coloured; coverts less so often but still sometimes. That review confirmed it's yellow warbler on structure... (e.g. bill shape)

Thanks to all.
